The holding portion that holds the operating portion and does not move even when the operating portion is operated together constitutes the operating portion.
In such a remote-operated drain plug device, when pushing/pulling-up operation is applied to the operating body, the inner wire of the release wire is moved to the valve member side and moved to the advancing/operating portion side in response to the operation of the operating body. Retracting (hereinafter, the movement of the inner wire to the valve member side is referred to as "advancement", the movement to the operating portion side is referred to as "retraction"), the inner wire end portion, or the shaft fixed to the inner wire end portion, etc. The valve member is pushed up to open the drainage port/the valve member is lowered by its own weight as the end portion of the inner wire is lowered, and the drainage port is closed. In this way, the drainage port can be opened and closed by remote operation by operating the operating body of the operation unit located away from the drainage port and the valve member.

Japanese Patent Laid-Open No. 10-227053

The remote-operated drain plug device configured as described above has the following problems. The drainage pipe including the remote-operated drainage plug device of Patent Document 1 is one in which drainage in which various kinds of dust, hair, sand, fats and oils are mixed flows. Therefore, there is a demand for cleaning the inside of the drainage pipe that has been used to some extent. For cleaning the inside of a long and narrow pipe, a relatively easy method to clean without using special equipment is to insert a long and narrow brush from the drain into the drain pipe on the downstream side of the drain, It is to polish the sides. This is a relatively effective method for performing drainage piping consisting of a normal pipe body other than the remote-operated drain plug device, but for the remote-operated drain plug device described in Citation 1 Was not available in some cases. This is because the operating part of the remote control type drain plug device is arranged so as to project in the drain pipe part, particularly in the drainage flow path, and forms a narrow part on the flow path, so a brush or the like is formed in this narrow part. However, there is a problem that it is difficult to insert the cleaning tool. Even if a tool that can be inserted into a narrow area is prepared, it is necessary to properly apply a cleaning tool to the narrow area, but the working part originally located deep in the drainage port In addition to being difficult to see, there is also the problem that during cleaning work, the cleaning tool itself or the hand of the worker holding the cleaning tool covers the drain port, making it almost impossible for the worker to visually check the inside of the drain port. there were. The present invention has been made in view of the above problems, and provides a remote-operated drain plug device that can easily and reliably clean the inside of the drain pipe portion.

The present invention according to claim 1 includes a drain port provided on the bottom surface of the tank body, a valve member that opens and closes the drain port by vertical movement, and a drain pipe portion that is a drain pipe provided downstream of the drain port. In a remote-operated drain plug device, which is provided on the inner surface of the drain pipe section and which moves the valve member up and down, and an operation section which operates the operation of the operation section, the upper part of the operation section is the operation. a smooth continuously from the end parts, by operating the operating unit, the operating unit is configured to select one of a plurality of stationary state, and the at least stationary, at elevated state of the valve member Since the end portion of the working portion is substantially flush with the end portion of the inner surface of the adjacent drain pipe portion, the inner surface of the drain pipe portion at the position directly below the drain port is The remote operated drain plug device is characterized in that the inner surface is smooth, except for the connection points of the parts.
The "stationary state" here means "a state in which the user of the remote-controlled drainage plug device maintains the state when the remote-operated drainage plug device is not operated." To point to. For example, in a remote-operated drain plug device, the user completes the operation on the operation unit and finishes adding the operation to the operation unit, and maintains the drain port open. The "open state" and the "closed state" in which the drainage port is maintained in a closed state are both "stationary states". On the other hand, when the user operates the operation part from the closed state to the open state by operating the operation part, the user of the remote control type drain plug device operates the operation part to raise the valve member. The state is not a static state because "the user is operating the operation unit" and "the state where the valve member is raised cannot be maintained when the user stops the operation of the operation unit".
In addition, "the inner surface of the drain pipe section at the position directly below the drain port is smooth" means that there are almost no steps or protrusions on the inner surface in the drain pipe section downstream from the drain port in the range immediately below the drain port. Means not to. The term "substantially absent" means that it is 3 mm or less in a direction substantially perpendicular to the inner surface of the tubular body (for example, in the case of a tubular body, the central axis direction of the tubular body, and if it is a bottom surface, it is an upward direction), preferably 3 mm or less. Since a minute protrusion or step of about 1 mm or less does not become an obstacle when performing cleaning by inserting an instrument from the drain port, even if such a minute protrusion or step exists, it is functionally functional. It is treated as "the inner surface is smooth".
In addition, the drainage holes provided in the drainage pipe section for inflowing the drainage from other pipes and/or for discharging the drainage to other pipes should be “holes” instead of “inner surfaces” of the drainage flow paths. However, since there is no surface that needs to be cleaned, even if there is a drain hole in the drain pipe section, the smoothness of the inner surface cannot be denied because of that.

The present invention according to claim 2 includes a drainage port provided on the bottom surface of the tank body, a valve member that opens and closes the drainage port by vertical movement, and a drainage pipe portion that is a drainage pipe provided downstream of the drainage port. In the remote-operated drain plug device, which comprises an operating part which is provided on the inner surface of the drain pipe part and moves the valve member up and down, and an operating part which operates the operation of the operating part, the drain pipe part is It is provided with a bending portion that bends at a position directly below, and the upper portion of the operating portion is continuously smooth from the end portion of the operating portion, and the operating portion operates in any of a plurality of stationary states depending on the operation of the operating portion.

It is a drain plug device.
The term "gap in the range that does not interfere with the operation of the operating part" as used herein means that the clearance when the end of the operating part is flush with the end of the inner surface of the adjacent drain pipe part is 1.0 mm. It indicates a gap having the following width.

The present invention according to claim 4 is characterized in that the stationary state of the remote-operated drain plug device comprises a drain port opening state and a drain port closed state. The remote-operated drain plug device according to any one of the above.

According to a fifth aspect of the present invention, the stationary state of the remote-operated drainage plug device includes a drainage port open state, a drainage port closed state, and a drainage port and a drainage pipe interior cleaning state. Is characterized by. The remote-operated drain plug device according to any one of paragraphs 0005 to 0007 .

As described above, the construction of the remote control type drain plug device of the first embodiment of the present invention is completed.
In the state in which this construction is completed, the drainage port 1a to the drainage port body 1, the joint member 3, the overflow pipe 7, and the S-shaped pipe body P serve as a drainage pipe portion. Of these, the vertical pipe portion 3a and the bottom portion inside the drain outlet body 1 and inside the joint member 3 correspond to the inner surface of the drain pipe portion at the position directly below the drain outlet 1a, and the position directly below the drain outlet 1a. In the inner surface portion of the drain pipe portion, except for the storage portion 3d and the hair catcher step portion 1d, there is no protrusion or step portion D in a direction substantially perpendicular to the inner surface, and the inner surface has a smooth structure. There is.
In addition, in this embodiment, since the inner diameter is also the same at the connection point between the drain port body 1 and the joint member 3, no step is generated at the connection point of the pipe body.
The remote-operated drain plug device of the present embodiment configured as described above is a remote-operated drain plug device in which the pushing-up member 8, that is, the operating portion is arranged in the bent portion 3b.

The operation of the remote-operated drain plug device of the first embodiment will be described below.
When the remote operated drain plug device of the first embodiment is used, as shown in FIG. 2, first, the operation body 4a of the operation portion 4 is operated to cover the drain port 1a with the valve body 2a of the valve member 2. The drainage port 1a is closed and is in a stationary state.
At this time, the operating body 4a of the operating portion 4 is pulled up, and the push-up member 8 to which the operation of the operating body 4a is transmitted via the inner wire 5b is pulled down by the inner wire 5b and descends downward, so that the valve member It is separated from the lower end of the second valve shaft 2b. The push-up member upper surface 8a is separated from the inner bottom surface of the joint member 3 to form a step.
In the stationary state in which the drain port 1a is closed, friction between the annular packing R provided on the operating body 4a and the inner surface of the operating portion main body 4c, and the annular packing R provided on the pushing-up member 8 and the storage state. It is maintained by the friction of the contact with the inner surface of the portion 3d.
When a downward pushing operation is applied to the operating body 4a of the operating portion 4 from this state, the operating body 4a is lowered, and the pushing-up member 8 is pushed up via the inner wire 5b to rise in the storage portion 3d. When the operating body 4a is pushed to the lower limit, as shown in FIG. 3, the pushing-up member upper surface 8a becomes flush with the bottom surface of the inner surface of the joint member 3, and the pushing-up member upper surface 8a and the inner bottom surface of the joint member 3 come together. The step disappears and the robot becomes stationary.
At this time, the valve member 2 is supported by the valve shaft 2b in order to further push up the valve shaft 2b after the lifted up member 8 contacts the lower end of the valve shaft 2b of the valve member 2 located in the storage portion 3d. The valve body 2a is separated from the drainage port 1a, and the drainage port 1a is opened and is in a stationary state.
Even when the drain port 1a is open, the friction between the annular packing R provided on the operation body 4a and the inner surface of the operation portion main body 4c and the annular packing R provided on the push-up member 8 and the storage state are stored. It is maintained by the friction of the contact with the inner surface of the portion 3d.
When there is spouting water or drainage in the wash bowl SB, the spouting water or drainage is finally discharged from the drain port 1a through the inside of the drain port body 1, the joint member 3, and the S-shaped pipe body P provided with the trap portion T. Is discharged from the underfloor piping to the sewage side. Further, when drainage is collected in the trap portion T, pooled water due to drainage called sealing water is generated in the trap portion T. This sealing water creates a full-filled portion on the drainage flow path. Odors and pests from the sewage side cannot flow back through the filled water portion of the sealing water, so that the trap portion T can prevent the odors and pests from the sewage side from entering the indoor side.
When the operation body 4a of the operation unit 4 is pulled up from the state in which the drainage port 1a is opened, the operation body 4a of the operation unit 4 is pulled up and the push-up member 8 is pulled by the inner wire 5b. Then, the push-up member upper surface 8a moves away from the bottom surface of the inner surface of the joint member 3 to a position where a step is formed. The valve member 2 loses the support of the push-up member 8 and descends, and the valve body 2a covers the drainage port 1a and returns to the stationary state in which the drainage port 1a shown in FIG. 2 is closed.
After that, the drain port 1a can be opened by pushing the operation body 4a downward, and the drain port 1a can be closed by pushing the operation body 4a upward. The open state and the closed state of the drainage port 1a are such that even if the user of the remote-operated drainage plug device finishes the operation on the operating body 4a and releases his/her hand, the annular packing R of the operating body 4a and the pushing-up member 8a is removed. It is maintained static by using friction.
When water is discharged into the washbasin SB with the drainage port 1a closed, or when the drainage port 1a is open, spouting water is generated in the washbasin SB to an extent that exceeds the drainage treatment capacity of the drainage port 1a. In this case, spouted water collects inside the wash bowl SB, and the water level in the wash bowl SB rises. However, when the water surface reaches the lower end position of the overflow port O, the spouted water in the wash bowl SB is discharged from the overflow port O in the order of the elbow pipe 7b, the hose pipe portion 7a, and the adapter portion 7c, and the lateral hole portion 1c of the drainage body 1 is discharged. Passes through the inside of the drainage port main body 1 and is finally discharged from the underfloor pipe to the sewage side through the joint member 3 and the S-shaped pipe body P including the trap portion T.

When cleaning the drainage pipe adopting the remote-operated drainage plug device of the first embodiment, the operating member 4a is pushed down to the limit and then the valve member 2 is removed from the drainage port 1a.
In this state, by pushing down the operating body 4a to the limit, the push-up member 8 rises and its upper surface 8a becomes flush with the bottom surface of the inner surface of the joint member 3, and the upper surface 8a of the push-up member 8a and the joint member 3 It is in a stationary state with no step between the inner surface and the bottom surface.
In this way, there is no step between the upper surface of the push-up member and the bottom surface of the inner surface of the joint member 3 and the surfaces are flush with each other, and the inside of the drain port body 1 and the joint member corresponding to the inner surface of the drain pipe portion immediately below the drain port 1a are provided. The vertical tube portion and the bottom surface portion of the inside of 3 have a smooth inner surface in which there are almost no protrusions or step portions D in a direction substantially perpendicular to the inner surface. That is, in the open state, which is one of the stationary states of the remote control type drain plug device of the first embodiment, the upper surface and the end portion of the operating portion (pushing member 8) are the end portions of the inner surface of the adjacent drain pipe portion. By being flush with, the inner surface of the drain pipe portion at the position directly below the drain port 1a is smooth.
In this way, since the inner surface of the drain pipe portion located directly below the drain port 1a is smooth and there is no narrow portion, a cleaning tool such as an elongated brush is drained from the drain port 1a to the downstream side of the drain port 1a. It is possible to easily clean the inner surface of the drainage pipe portion located directly below the drainage port 1a simply by inserting it into the pipe portion and polishing the inner side surface.
It is almost impossible for the operator to visually check the inside of the drainage port 1a because the operating part in the part deep from the drainage port 1a, the cleaning device itself, and the hand of the worker holding the cleaning device cover the drainage port 1a. The point is the same as the conventional example, but the inner surface of the drain pipe part located directly below the drain port 1a is smooth, and there is no narrow part, so insert a cleaning tool from the drain port 1a and properly It is possible to almost certainly clean the inner surface of the drainage pipe portion located directly below the drainage port 1a only by polishing.
After cleaning, by inserting the valve member 2 into the drain port 1a again and disposing the valve member 2 in the drain port body 1 and the joint member 3, it is possible to use the remote-operated drain plug device again. Becomes

It is in a state of hanging.
As described above, the construction of the remote control type drain plug device of the second embodiment of the present invention is completed.
In the state in which this construction is completed, the drainage port 1a to the drainage port body 1, the joint member 3, the overflow pipe 7, and the S-shaped pipe body P serve as a drainage pipe portion. Of these, the inside of the drainage port main body 1, the internal portion of the vertical pipe portion 3a of the joint member 3, and the portion of the inside of the S-shaped pipe body P that is visible from the drainage port 1a in plan view are located directly below the drainage port 1a. Corresponding to the inner surface of the drainage pipe portion in, and the inner surface portion of the drainage pipe portion immediately below the drainage port 1a includes a joint portion along the periphery of the drainage body 1 and the joint member 3, and (the inner peripheral surface and the surface). Except for the lever body 9 (in the state of not being one), there is no protrusion or step D in a direction substantially perpendicular to the inner surface, and the inner surface is smooth.
Further, in this embodiment, since the inner diameter is also the same at the connection portion between the joint member 3 and the S-shaped pipe body P, no step is generated even at the connection portion of the pipe body.
The remote-operated drain plug device of the present embodiment configured as described above is a remote-operated drain plug device in which the lever body 9 and the rod portion 5c, that is, the operating portion are arranged in the vertical pipe portion 3a. ..

The operation of the remote operated drain plug device of the second embodiment will be described below.
When using the remote operated drain plug device of the second embodiment, first, as shown in FIG. 5, the operation body 4a of the operation portion 4 is operated to cover the drain port 1a with the valve body 2a of the valve member 2. The drainage port 1a is closed and is in a stationary state.
At this time, the support shaft 6b of the lock member 6 is unlocked from the casing portion 6a, and the inner wire 5b is retracted toward the operating portion 4 side by the action of the return spring of the release wire 5 and the operating portion 4 The operating body 4a is pulled up. Since the inner wire 5b is retracted to the operation portion 4 side, the rod portion 5c connected to the inner wire 5b is also retracted and accommodated in the through hole 10a. Therefore, as shown in FIG. 7, the lever body 9 is in a state where the front surface of the lever body 9 faces the central axis direction of the vertical pipe portion 3 a of the joint member 3. Since the valve member 2 does not support the valve shaft 2b, the valve member 2 descends inside the drainage port main body 1 and the joint member 3, and the drainage port 1a is covered by the valve body 2a of the valve member 2 to close the drainage port 1a as described above. It is in a stationary state.
In this state, when the user pushes the operating body 4a of the operating section 4 downward and then the user releases the operating body 4a, the operating body 4a descends and is pushed into the support shaft 6b of the lock member 6. The operation will be performed. By pushing the support shaft 6b, the support shaft 6b of the lock member 6 is fixed in a state of being advanced to the joint member 3 side, and is pushed by the support shaft 6b so that the inner wire 5b and the rod portion at the end of the inner wire 5b are pushed. The 5c material is fixed in a state of being advanced to the central axis side of the vertical tube portion 3a.
When the rod portion 5c moving forward and backward through the through hole 10a moves forward toward the center of the vertical pipe portion 3a of the joint member 3 as described above, the tip of the rod portion 5c operates so as to push downward from the center of the rear surface of the lever body 9. As a result, the lever body 9 rotates about the rotary shaft 9a, and the valve shaft 2b and the valve body 2a at the tip of the valve shaft 2b are raised by scooping up the lower end of the valve shaft 2b of the valve member 2. As a result, as shown in FIG. 6, the valve body 2a is separated from the drain port 1a and the drain port 1a opens.
In this state, since the rod portion 5c is fixed in the advanced state, as shown in FIG. 8, the rod portion 5c goes around below the rear surface of the lever body 9 to support the lever body 9, and 1a is in a stationary state with an opening.
When there is spouting water or drainage in the wash bowl SB, the spouting water or drainage is finally discharged from the drain port 1a through the inside of the drain port body 1, the joint member 3, and the S-shaped pipe body P provided with the trap portion T. Is discharged from the underfloor piping to the sewage side. Further, when drainage is collected in the trap portion T, pooled water due to drainage called sealing water is generated in the trap portion T. This sealing water creates a full-filled portion on the drainage flow path. Odors and pests from the sewage side cannot flow back through the filled water portion of the sealing water, so that the trap portion T can prevent the odors and pests from the sewage side from entering the indoor side.
In this state, when the user pushes the operating body 4a of the operating portion 4 downward again, and then the user releases the operating body 4a, the operating body 4a descends again and the support shaft 6b of the lock member 6 is released. It will be pushed into. By pushing the support shaft 6b, the support shaft 6b of the lock member 6 once advances to the joint member 3 side, and then the support shaft 6b is released from the fixation, and the return spring of the inner wire 5b acts so that the inner wire 5b The support shaft 6b contacting the inner wire 5b and the operating body 4a are retracted toward the operating portion 4 side. In this way, when the rod portion 5c retracts toward the operation portion 4 side, the rod portion 5c is completely housed in the through hole 10a, the lever body 9 loses its support and rotates, and the front face of the vertical pipe portion 3a is rotated. Return to the state of facing the central axis.
The valve shaft 2b of the valve member 2 also loses its support, descends in the drainage body 1 and the joint member 3, and as shown in FIG. 5, the drainage port 1a is covered by the valve body 2a of the valve member 2 and the drainage port 1a. Return to the stationary state with the mouth closed.
After that, every time a downward pushing operation is applied to the operating body 4a, the valve shaft 2b of the valve member 2 and the valve body 2a are lifted and the drainage port 1a is opened. The shaft 2b and the valve body 2a can be lowered to alternately select the drain port 1a.
When the drain port 1a is closed by the weight of the lever body 9 and the valve member 2, and when the drain port 1a is opened by the lock mechanism of the lock member 6, the user of the remote control type drain plug device finishes the operation of the operation body 4a. , Even if you release your hand, it will be kept still.
When water is discharged into the washbasin SB with the drainage port 1a closed, or when the drainage port 1a is open, spouting water is generated in the washbasin SB to an extent that exceeds the drainage treatment capacity of the drainage port 1a. In this case, spouted water collects inside the wash bowl SB, and the water level in the wash bowl SB rises. However, when the water surface reaches the lower end position of the overflow port O, the spouted water in the wash bowl SB is discharged from the overflow port O in the order of the elbow pipe 7b and the hose pipe, and passes through the S-shaped pipe body P having the trap portion T. Finally, it is discharged from the underfloor piping to the sewage side.

When cleaning the drainage pipe adopting the remote operated drainage plug device of the second embodiment, the drainage port 1a is closed by operating the operation body 4a, and then the valve member 2 is removed from the drainage port 1a. The valve member 2 is removed (or the valve member 2 is removed and then the operation portion 4 is operated to bring it into a closed state).
In this state, the rod portion 5c is retracted to the operation portion 4 side, so that the lever body 9 loses its support and rotates by its own weight, and the front surface of the lever body 9 is the center of the vertical pipe portion 3a of the joint member 3. It becomes stationary at the position facing the axis.
At this time, there is no step between the front surface of the lever body 9 and the inner side surface of the joint member 3, and the inside of the drainage port main body 1 and the vertical pipe of the joint member 3 corresponding to the inner surface of the drainage pipe portion immediately below the drainage port 1a. The inner portion of the portion 3a and the portion of the inside of the S-shaped tubular body P that is visible from the drain port 1a in plan view have no protrusions or step portions D in a direction substantially perpendicular to the inner surface. Due to the smooth structure, in the closed state, which is one of the stationary states of the remote control type drain plug device of the second embodiment, the front surface and the end portion of the lever body 9 which is a part of the operating portion are By being flush with the inner side surface of the end portion of the inner surface of the adjacent drainage pipe part, the inside of the drainage port main body 1 which is the drainage pipe part immediately below the drainage port 1a, the vertical pipe part 3a of the joint member 3, and A portion of the inside of the S-shaped pipe body P that is visible from the drain port 1a in plan view has a smooth inner surface.
Further, in this embodiment, when the end portion of the lever body 9 which is the operating portion is flush with the end portion of the inner surface of the vertical pipe portion 3a of the joint member 3 which is the adjacent drain pipe portion, the end portion of the operating portion is The part and the end of the inner surface of the joint member 3 adjacent to the part are configured so as to narrow the gap as long as they do not interfere with the operation of the operating part. Specifically, when the front surface of the lever body 9 and the inner surface of the joint member 3 are flush with each other, the gap between the side surface of the lever body 9 and the end portion of the inner surface of the adjacent joint member 3 is 1.0 mm or less. Is about 0.1 mm.
Further, in order to have such a width, the following measures are taken in this embodiment.
As described in paragraph 0017, the side surface of the lever body 9 has a trapezoidal shape (planar trapezoidal shape) in plan view, and both side surfaces are wider toward the front side with respect to the rotating shaft 9a of the lever body 9. It is equipped with a slope. On the other hand, the inner surface of the branch pipe portion 3e is a plane perpendicular to the rotation axis 9a of the lever body 9.
Accordingly, when the front surface of the lever body 9 and the inner surface of the joint member 3 are flush with each other, the gap between the side surface of the lever body 9 and the end portion of the inner surface of the joint member 3 that is adjacent to the side surface of the joint body 3 becomes the smallest, and the other lever body 9 Since the gap can be sufficiently widened in the operating state such as the rotating state of the lever body, there is no hindrance to the operation of the lever body 9 which is the operating portion, and the lever body 9 is flush with the inner surface of the joint member 3. The gap between the nine side surfaces and the end portion of the inner surface of the adjacent joint member 3 can be set to a sufficiently narrow range of about 0.1 mm.
In this way, since the inner surface of the drain pipe portion located directly below the drain port 1a is smooth and there is no narrow portion, a cleaning tool such as an elongated brush is drained from the drain port 1a to the downstream side of the drain port 1a. It is possible to easily clean the inner surface of the drainage pipe portion located directly below the drainage port 1a simply by inserting it into the pipe portion and polishing the inner side surface.
It is almost impossible for the operator to visually check the inside of the drainage port 1a because the operating part in the part deep from the drainage port 1a, the cleaning device itself, and the hand of the worker holding the cleaning device cover the drainage port 1a. The point is the same as the conventional example, but the inner surface of the drain pipe part located directly below the drain port 1a is smooth and there is no narrow part, so insert a cleaning tool from the drain port 1a and properly It is possible to almost certainly clean the inner surface of the drainage pipe portion located directly below the drainage port 1a only by polishing.
Further, a step is formed at the joint between the drainage body 1 and the joint member 3, but this step is formed in the same cross-sectional shape along the entire joint of the inner peripheral surface along the joint, and By moving the cleaning jig along the cleaning tool, cleaning can be easily performed without visually observing the step portion, so that there is no problem that the cleaning performance is deteriorated.
After cleaning, by inserting the valve member 2 into the drain port 1a again and disposing the valve member 2 in the drain port body 1 and the joint member 3, it is possible to use the remote-operated drain plug device again. Becomes

The branch pipe portion 3e has a rotation groove 3f for allowing the rotary shaft 9a of the lever body 9 to pass therethrough from the end thereof and for accommodating the rotation shaft 3f so as to be parallel to the axis of the branch pipe portion 3e. Then, it is formed from the end of the branch pipe portion 3e to the vicinity of the vertical pipe portion 3a. The rotation groove 3f does not reach the inside of the vertical pipe portion 3a, and when the construction is completed, the lever body 9 rotates about the end of the rotation groove 3f on the vertical pipe portion 3a side.
In addition, in the inner portion below the opening of the upstream end of the joint member 3 (the inner portion below the position directly below the drainage port 1a when the construction is completed), the vertical pipe portion 3a is circular as viewed in the axial direction. In addition, the inner peripheral surface of the vertical pipe portion 3a, the inclined portion, and the bottom surface portion form a smooth surface with no irregularities.

The operating body 4a is a substantially rod-shaped member having a knob portion 4b that is pushed by the user of the remote control type drain plug device when it is used, and is configured to slide inside the operating portion main body 4c. Unlike the operating body 4a of the first embodiment, the annular packing R and the like are not provided. Therefore, when the operating body 4a is inserted into the operation portion main body 4c, which will be described later, the operating body 4a is not supported at all. The lower end of the knob portion 4b descends (falls) until it comes into contact with the upper surface of the operation portion main body 4c.
The operation portion main body 4c is a substantially cylindrical member attached near the upper edge of the washbasin SB, and has a flange portion 4d at the upper edge, and the operation body 4a can be moved up and down and removed. The lock mechanism connected to the release wire 5 is connected and fixed to the lower end of the cylindrical portion while being housed impossible.
The operating portion is composed of a lever body 9, a spacer 10, and a rod portion 5c of the release wire 5 described below.

It has a rotary shaft 9a which is inserted and rotates around the end of the rotary groove 3f on the side of the vertical pipe portion 3a.
In addition, the "front surface" of the lever body 9 here is "a surface parallel to the inclined surface 3g in a state where the construction of the remote control type drain plug device is completed and the drain port 1a is closed". Is referred to as a top surface, a bottom surface, a side surface, and a back surface. Also in the following description, when "front of the lever body 9", "rear surface of the lever body 9" and the like are described, no matter which direction the lever body 9 is facing, the above-mentioned "remotely operated drain plug" When the construction of the device is completed and the drainage port 1a is closed, the "face of the lever body 9 seen when the direction of the branch pipe portion 3e is viewed from the central axis of the vertical pipe portion 3a of the drainage joint" is referred to as "front face". It is described as "front", "back", etc.
Separately from this, when the directions “above the lever body 9” and “below” are described, they indicate “above” and “below” the position where the lever body 9 exists at that time.
Further, the surface forming the “front” of the lever body 9 is in a state where the construction is completed, the support of the rod portion 5c is lost, the lever body 9 descends, and the drain port 1a is closed (the lower end of the front surface of the lever body 9 is It is designed and configured to be a flat surface that is continuous with the inclined surface 3g in the state of being in contact with the bottom surface of the joint member 3).
The spacer 10 is a member arranged inside the branch pipe portion 3e, and is inserted into the branch pipe portion 3e after the lever body 9 is inserted, thereby eliminating the gap for the lever body 9 to move. The branch pipe portion 3e is positioned so that it may rotate about the rotary shaft 9a but does not move toward the end in the branch pipe portion 3e.
Further, the spacer 10 has a through hole 10a through which the rod portion 5c of the release wire 5 advances and retreats, and guides the rod portion 5c to advance and retract in order to rotate the lever body 9. More specifically, when the construction is completed, the through hole 10a is arranged in the branch pipe portion 3e so as to be located near the lower portion of the rotation groove. When the rod portion 5c is housed in the through hole 10a, the lever body 9 is in a state where the front surface is directed to the center of the vertical pipe portion 3a. When the rod portion 5c moving forward and backward through the through hole 10a moves forward to the center side of the vertical pipe portion 3a of the joint member 3, the tip of the rod portion 5c operates so as to push below the rear surface of the lever body 9, whereby the lever body 9 Is rotated and the front surface of the lever body 9 is rotated upward around the rotation shaft 9a. When the rod portion 5c retreats toward the operation portion 4 side, the rod portion 5c is completely housed in the through hole 10a, and the lever body 9 returns to the state in which the front surface is directed to the central axis direction of the vertical tube portion 3a.
The release wire 5 is an operation transmission member for transmitting an operation applied to the operation portion 4 to the valve member 2, and is formed into a tubular shape and has rigidity in the axial direction and flexibility in the side direction. The tube 5a, an inner wire 5b that is slidably movable in the outer tube 5a and has rigidity in the axial direction and flexibility in the side direction, and the inner wire 5b is located on the operation portion 4 side with respect to the outer tube 5a. Return spring (not shown) disposed in the outer tube 5a, the rod portion 5c provided at the end portion of the inner wire 5b on the drain outlet 1a side, and the end portion of the branch pipe portion 3e when the construction is completed. And a cap body 5d that closes the.
The cap body 5d that closes the branch pipe portion 3e is configured such that the release wire 5 is inserted therethrough.
A lock member 6 described below is connected and fixed to an end portion of the release wire 5 on the operation portion 4 side.
The lock member 6 includes a casing portion 6a and a support shaft 6b slidably provided in the casing portion 6a. The inside of the casing portion 6a and the support shaft 6b are provided with a lock mechanism (not described in detail). The outer tube 5a is configured to be connected to the casing portion 6a, and when the outer tube 5a is connected to the casing portion 6a, the inner wire 5b is arranged such that the end portion of the inner wire 5b abuts the support shaft 6b. Become.
When the pushing operation is performed on the support shaft 6b in the state where the lock member 6 is connected to the release wire 5, that is, the casing portion 6a is connected to the end portion of the outer tube 5a, the support shaft 6b moves forward for each pushing operation, The inner wire 5b and the support shaft 6b are alternately retracted to the operation portion 4 side by the action of the return spring of the release wire 5 while the inner wire 5b is pushed forward by the support shaft 6b and is fixed. It is configured to repeat.
The S-shaped pipe body P is a member that is connected to the downstream end of the joint member 3 and is formed by bending the pipe body into an S-shape, and the S-shaped portion functions as the trap portion T. The upstream end of the S-shaped pipe portion is formed in the horizontal direction, and the downstream end is connected to an underfloor pipe that is piped below the floor surface on which the washbasin S is constructed.
Further, a straight pipe member 7d of the overflow pipe 7 to be described later is connected on the upstream side of the trap portion T and above the vertical portion of the pipe body that is bent in the S shape.
The overflow pipe 7 is a pipe through which drainage flows from the overflow port O into the lateral hole portion 1c of the drainage body 1, and has a flexible hose pipe portion 7a and an overflow provided at one end of the hose pipe portion 7a. It is composed of an elbow pipe 7b connected to the mouth O and a straight pipe member 7d provided at the other end of the hose pipe.

The remote-operated drain plug device of the third embodiment configured as described above is installed on the wash basin S including the wash basin SB which is a tank body in the following manner. In addition, even if not particularly described, the connection points of the respective members are water-tightly connected by screw connection using an adhesive or packing as necessary.
First, in advance, the operating body 4a is inserted and fixed in the operating body 4c near the upper edge of the washbasin SB.
Next, the operating portion is attached to the branch pipe portion 3e of the joint member 3. This mounting work will be described in detail. First, the lever body 9 is inserted from the end of the branch pipe portion 3e while the rotation shaft 9a of the lever body 9 is aligned with the rotation groove of the branch pipe portion 3e. Is moved until it reaches the end of the rotary groove on the side of the vertical pipe portion 3a. Next, the spacer 10 is inserted into the branch pipe portion 3e so that the lever body 9 can rotate about the rotation shaft 9a but cannot move inside the branch pipe portion 3e.
Next, after inserting the rod portion 5c at the end portion of the inner wire 5b of the release wire 5 into the through hole 10a of the spacer 10, the end portion of the outer tube 5a is brought into contact with the spacer 10, and the cap body 5d further branches the pipe. By connecting and fixing the end portion of the outer tube 5a to the branch pipe portion 3e while closing the portion 3e, the work of attaching the operating portion to the branch pipe portion 3e is completed.
Next, the drainage tubular body is inserted into the upstream end of the joint member 3, and then the cap nut F locked to the drainage tubular portion 11 is screwed onto the male screw of the joint member 3 to be connected and fixed. In order to screw the cap nut F of the drainage tubular portion 11 and the male screw of the coupling member 3 in a state where the drainage tubular portion 11 is arranged so as to be inserted into the vertical pipe portion 3a of the joint member 3, The lower end of the drainage tubular portion 11 becomes a step portion D along the entire circumference of the drainage tubular portion 11 and the inner peripheral surface of the joint member 3.
Next, the downstream end of the joint member 3 is connected to the upstream end of the S-shaped pipe P, and the downstream end of the S-shaped pipe P is connected to the underfloor piping.
Next, the elbow pipe 7b of the overflow pipe 7 is connected to the overflow port O of the wash bowl SB from the back side. Further, the straight pipe member 7d provided at the end of the hose pipe of the overflow pipe 7 is connected by inserting it into the connecting pipe portion of the S-shaped pipe body P. This causes the lower end of the straight pipe member 7d to enter a part of the trap portion T.
Next, the end portion of the release wire 5 on the operating portion 4 side is connected to the operating portion 4. This connection will be described in detail. After the lock member 6 is connected to the end portion of the release wire 5 on the operation portion 4 side, the casing portion 6a of the lock member 6 is connected to the lower end of the operation portion main body 4c. At this time, the lower end of the operating body 4a is arranged at a position where it abuts on the upper end of the support shaft 6b.
Further, the valve member 2 is arranged from the drain port 1a to the inside of the drain port body 1 and the joint member 3, and the outer surface of the hair catcher 2c of the valve member 2 is brought into contact with the inner surface of the drain tube portion 11.
As described above, the construction of the remote control type drain plug device of the third embodiment of the present invention is completed.
When this construction is completed, the drainage pipe portion 11 to the drainage pipe portion 11, the inside of the joint member 3, the overflow pipe 7, and the S-shaped pipe body P serve as a drainage pipe portion. Of these, the drainage tubular portion 11, the inner portion of the vertical pipe portion 3a of the joint member 3, and the inclined surface 3g and the bottom portion of the joint member 3 correspond to the inner surface of the drainage pipe portion immediately below the drainage port 1a (the joint portion). The inner portion of the vertical pipe portion 3a of the member 3 has a larger diameter in plan view than the drainage port 1a, and is not exactly "the inner surface of the drainage pipe portion immediately below the drainage port 1a", but from above. Since it is a visible range when the drainage port 1a is visually recognized, it is included here as "the inner surface of the drainage pipe part directly below the drainage port 1a"), the inner surface of the drainage pipe part immediately below these drainage ports 1a. Except for the joint portion along the peripheral edges of the drainage port main body 1 and the joint member 3 and the lever body 9, there is no protrusion or step D in a direction substantially perpendicular to the inner surface, and the inner surface is smooth. It is composed.
The remote-operated drain plug device of the present embodiment configured as described above is a remote-operated drain plug device in which the lever body 9 and the rod portion 5c, that is, the operating portion are arranged on the bent portion 3b.

The operation of the remote operated drain plug device of the third embodiment will be described below.
When the remote operated drain plug device of the third embodiment is used, as shown in FIG. 12, first, the operation body 4a of the operation portion 4 is operated to cover the drain port 1a with the valve body 2a of the valve member 2. The drainage port 1a is closed and is in a stationary state.
At this time, the support shaft 6b of the lock member 6 is unlocked from the casing portion 6a, and the inner wire 5b is retracted toward the operating portion 4 side by the action of the return spring of the release wire 5 and the operating portion 4 The operating body 4a is pulled up. Since the inner wire 5b is retracted to the operation portion 4 side, the rod portion 5c connected to the inner wire 5b is also retracted and accommodated in the through hole 10a. Therefore, as shown in FIG. 14, the lever body 9 has a front surface flush with the inclined surface 3g of the joint member 3. Since the valve member 2 does not support the valve shaft 2b, the valve member 2 descends inside the drainage port main body 1 and the joint member 3, and the drainage port 1a is covered by the valve body 2a of the valve member 2 to close the drainage port 1a as described above. It is in a stationary state.
In this state, when the user pushes the operating body 4a of the operating section 4 downward and then the user releases the operating body 4a, the operating body 4a descends and is pushed into the support shaft 6b of the lock member 6. The operation will be performed. By pushing the support shaft 6b, the support shaft 6b of the lock member 6 is fixed in a state of being advanced to the joint member 3 side, and is pushed by the support shaft 6b so that the inner wire 5b and the rod portion at the end of the inner wire 5b are pushed. The 5c material is fixed in a state of being advanced to the central axis side of the vertical tube portion 3a.
When the rod portion 5c that moves forward and backward through the through hole 10a moves forward toward the center of the vertical pipe portion 3a of the joint member 3 as described above, the tip of the rod portion 5c operates so as to push below the rear surface of the lever body 9. Thus, the lever body 9 rotates about the rotation shaft 9a and pushes up the lower end of the valve shaft 2b of the valve member 2 to raise the valve shaft 2b and the valve body 2a at the tip of the valve shaft 2b. As a result, as shown in FIG. 13, the valve body 2a is separated from the drain port 1a and the drain port 1a opens.
In this state, since the rod portion 5c is fixed in the advanced state, as shown in FIG. 15, the rod portion 5c goes around below the rear surface of the lever body 9 to support the rod portion 5c, and the drain port 5c. 1a is in a stationary state with an opening.
When there is spouting water or drainage in the wash bowl SB, the spouting water or drainage is finally discharged from the drain port 1a through the inside of the drain tube portion 11, the joint member 3, and the S-shaped pipe body P provided with the trap portion T. Is discharged from the underfloor piping to the sewage side. Further, when drainage is collected in the trap portion T, pooled water due to drainage called sealing water is generated in the trap portion T. This sealing water creates a full-filled portion on the drainage flow path. Odors and pests from the sewage side cannot flow back through the filled water portion of the sealing water, so that the trap portion T can prevent the odors and pests from the sewage side from entering the indoor side. Further, the straight pipe member 7d of the overflow pipe 7 has its lower end arranged in this water sealing portion, and even if the drainage from the drainage port 1a is mixed with a component such as a detergent that causes bubbles, the overflow pipe 7d. Bubbles do not cause backflow on the 7 side. This is because the specific gravity of the bubbles is lighter than that of water and floats on the water, so that the bubbles cannot reach the lower end of the straight pipe member 7d below the water surface of the sealing water.
In this state, when the user pushes the operating body 4a of the operating portion 4 downward again, and then the user releases the operating body 4a, the operating body 4a descends again and the support shaft 6b of the lock member 6 is released. It will be pushed into. By pushing the support shaft 6b, the support shaft 6b of the lock member 6 once advances to the joint member 3 side, and then the support shaft 6b is released from the fixation, and the return spring of the inner wire 5b acts so that the inner wire 5b The support shaft 6b contacting the inner wire 5b and the operating body 4a are retracted toward the operating portion 4 side. In this way, the rod portion 5c retracts toward the operation portion 4 side, the rod portion 5c is completely housed in the through hole 10a, the lever body 9 loses its support and rotates, and as shown in FIG. The lever body 9 returns to the state in which the front surface is flush with the upper surface of the inclined surface 3g.
The valve shaft 2b of the valve member 2 also loses its support, descends within the drain body 1 and the joint member 3, and is stationary with the valve body 2a of the valve member 2 covering the drain port 1a and closing the drain port 1a. Return to the state.
After that, every time a downward pushing operation is applied to the operating body 4a, the valve shaft 2b of the valve member 2 and the valve body 2a are lifted and the drainage port 1a is opened. The shaft 2b and the valve body 2a can be lowered to alternately select the drain port 1a.
When the drain port 1a is closed by the weight of the lever body 9 and the valve member 2, and when the drain port 1a is opened by the lock mechanism of the lock member 6, the user of the remote control type drain plug device finishes the operation of the operation body 4a. , Even if you release your hand, it will be kept still.
When water is discharged into the washbasin SB with the drainage port 1a closed, or when the drainage port 1a is open, spouting water is generated in the washbasin SB to an extent that exceeds the drainage treatment capacity of the drainage port 1a. In this case, spouted water collects inside the wash bowl SB, and the water level in the wash bowl SB rises. However, when the water surface reaches the lower end position of the overflow port O, the spouted water in the wash bowl SB is discharged from the overflow port O in the order of the elbow pipe 7b and the hose pipe, and passes through the S-shaped pipe body P having the trap portion T. Finally, it is discharged from the underfloor piping to the sewage side.

When cleaning the drainage pipe which employs the remote operated drainage plug device of the third embodiment, the drainage port 1a is closed by operating the operating body 4a, and then the valve member 2 is removed from the drainage port 1a. The valve member 2 is removed (or the valve member 2 is removed and then the operation portion 4 is operated to bring it into a closed state).
In this state, the rod portion 5c is retracted to the operation portion 4 side, so that the lever body 9 loses its support and rotates by its own weight, so that the front surface of the lever body 9 is parallel to the inclined surface 3g of the joint member 3 and It will be in a stationary state at a level position.
At this time, since there is no step between the front surface of the lever body 9 and the inclined surface 3g that is a part of the inner side surface of the joint member 3, the drainage tubular portion corresponding to the inner surface of the drainage pipe portion immediately below the drainage port 1a. 11 Inside, the internal portion of the vertical pipe portion 3a of the joint member 3, the inclined surface 3g, and the bottom surface portion of the joint member 3 immediately below the drainage port 1a are substantially perpendicular to the inner surface except the joint portion of the drainage pipe body. Since there is no protrusion or step portion D on the inner surface and the inner surface has a smooth structure, the operating portion of the remote control type drain plug device according to the third embodiment is in a closed state, which is one of the stationary states. The end portion is flush with the end portion of the inner surface of the adjacent drain pipe portion, so that the drain pipe portion at the position directly below the drain port 1a has a smooth inner surface.
Further, in this embodiment, when the end portion of the lever body 9 which is the operating portion is flush with the inclined surface 3g of the joint member 3 which is the adjacent drain pipe portion, the inclined surface which is adjacent to the end portion of the operating portion. The end portion of 3 g is configured to have a narrow gap within a range that does not interfere with the operation of the operating portion. Specifically, when the front surface of the lever body 9 is flush with the inclined surface 3g, the gap between the side surface of the lever body 9 and the end of the inner surface of the slit portion 3h has a width of 1.0 mm or less. It is about 1 mm.
Further, in order to have such a width, the following measures are taken in this embodiment.
As described in paragraph 0021, the side surface of the lever body 9 has a trapezoidal shape in plan view (isosceles trapezoidal shape), and both side surfaces are wider toward the front side with respect to the rotating shaft 9a of the lever body 9. It is equipped with a slope. On the other hand, the inner surface of the slit portion 3h is a plane perpendicular to the rotation axis 9a of the lever body 9.
Accordingly, when the front surface of the lever body 9 and the inclined surface 3g are flush with each other, the gap between the side surface of the lever body 9 and the end portion of the inner surface of the slit portion 3h adjacent to the side surface is the smallest, and the other lever bodies 9 have the same gap. Since the gap can be made sufficiently wide in an operating state such as a rotating state, there is no hindrance to the operation of the lever body 9 which is an operating portion, and the side surface of the lever body 9 when the front surface of the lever body 9 and the inclined surface 3g are flush with each other. Then, the gap between the end of the inner surface of the adjacent slit portion 3h can be set to a sufficiently narrow range of about 0.1 mm.
In this way, since the inner surface of the drain pipe portion located directly below the drain port 1a is smooth and there is no narrow portion, a cleaning tool such as an elongated brush is drained from the drain port 1a to the downstream side of the drain port 1a. It is possible to easily clean the inner surface of the drainage pipe portion located directly below the drainage port 1a simply by inserting it into the pipe portion and polishing the inner side surface.
It is almost impossible for the operator to visually check the inside of the drainage port 1a because the operating part in the part deep from the drainage port 1a, the cleaning device itself, and the hand of the worker holding the cleaning device cover the drainage port 1a. The point is the same as the conventional example, but the inner surface of the drain pipe part located directly below the drain port 1a is smooth, and there is no narrow part, so insert a cleaning tool from the drain port 1a and properly It is possible to almost certainly clean the inner surface of the drainage pipe portion located directly below the drainage port 1a only by polishing.
Further, although a step is formed at the joint between the drainage tubular portion 11 and the joint member 3, the step is formed in the same cross-sectional shape along the entire joint of the inner peripheral surface along the joint, and By moving the cleaning jig along the cleaning tool, cleaning can be easily performed without visually observing the step portion, so that there is no problem that the cleaning performance is deteriorated.
After cleaning, by inserting the valve member 2 into the drain port 1a again and disposing the valve member 2 in the drain port body 1 and the joint member 3, it is possible to use the remote-operated drain plug device again. Becomes
